Hi again,
First of all, the item you pointed to on eBay is a fiberglass fender, no doubt made by someone in the aftermarket since Triumph never put f'glass on the cars.
There are pluses and minuses to these. One big minus is that it probably lower the value of the car in most cases. Buyers generally avoid fiberglass reproduction parts. Plus, aftermarket parts like these can vary alot in quality and fit, from great to pretty poor. Well-made fiberglass parts are strong and hold up well. F'glass does dry out over time, though, so usually isn't as long-lived as properly protected 18 gauge steel. And, there is always the concern about how to join fiberglass parts to metal parts. Not a major problem with a bolt-on fender like this, but anything that would normally be welded will need to be riveted or use some other means of fastening.
On the plus side, concerns about rust are reduced by using fiberglass parts. Fiberglass is also relatively easy to repair or modify, if that's important. It is also lighter weight, which is why you find it on many vintage race cars.
As to using eBay... Whew! Short question... Long answer!
I've had hundreds of transactions there over the past 5 or 6 years, both as a buyer and seller, mostly of car parts, motorcycle parts and collectible cameras and lenses. 99% of sellers and buyers are easy to work with and totally honest. Out of maybe a total of 1000 transactions, I can only point to one or two where I suspected someone was deliberately trying to rip me off.
There are few problems and the overall system is easy to use. eBay uses "feedback" as a rating system, where sellers and buyers both usually receive and leave comments about each other after each transaction. This shows up in each item a seller lists, and let's you know their track record. Always look closely at this before bidding! A lot of negatives might indicate a problem to be avoided!
Many eBay sellers are small businesses, dependent upon their auctions for their income. Their feedback rating is their reputation and they work hard to protect it while increasing the postive responses. If you ever have a problem, try via email or whatever means to resolve it satisfactorily before leaving negative feedback. Once it's left, it cannot be retracted!
Beyond feedback, a seller who abuses the system badly can be banned from eBay entirely. For many, this would mean they are essentially "put out of business" or "fired from their job"!
When you are brand new to eBay, you will have a "zero feedback" rating, which might concern some sellers. They may ask you to get in touch before bidding, as reassurance that you are serious, know how the process works and have done the necessary preparations.
Speaking of which, one thing to do to prepare to bid and buy on eBay is to figure out how you want to pay for items. Sellers expect winning bidders to pay in a reasonably short time, say 3 to 10 days. So, that means using something like PayPal, which costs buyers nothing (but does charge sellers, so some don't use it) or planning to go get a money order and mail it promptly.
Communication is key. I've mentioned using emails to pre-clarify several things already. It's also very important after winning an auction to quickly get in touch and make arrangements to pay for the item.
Once an auction is won, there is no turning back and you have commited to follow through on the purchase. Failure to do so will get you negative feedback at least, and possibly banned from using eBay entirely, if it happens repeatedly.
One concern, many sellers don't have very detailed knowledge about the items they sell. Many buy at a local auction or estate sale and simply turn around and market a wide variety of things. Some will even tell you so right in their listings! They might give incorrect, incomplete or misleading information, throwing you off. Look at photos closely and email with questions before bidding. It's great when you come across a private party who is personally knowledeable about the stuff they are selling, and gladly shares that info. But, that's really pretty uncommon.
Watch out for high shipping charges, too. Many sellers make up for low, low prices with added "handling" fees. If they don't tell you how much shipping will be in the listing, email in advance and find out before bidding.
Because you are in Canada, you might especially be concerned about shipping. I understand, for example, that one major shipper (UPS?) is ruthless about charging fees to cover your country's import duties. Others are more reasonable (US Post Office?).
Some sellers try to avoid "international" sales, too, and usually say so in their listings. But, often you can email them, they might bend their rules if you ask.
In general, I usually don't bid on something I'm not totally familiar with, until I've seen a few transactions and/or carefully explored how much it might cost me elsewhere. Sometimes eBay prices are higher than local retail!
Hope this helps!
Alan
