Careful, Doc, there's a rule about posting porn, and that naked 1750 comes awful close! (You had a GT Junior? Coool...)
There are a lot of similarities between Alfas and LBC's in concept; they should get along well together. Old Alfas tend to be mechanically "pure," there's not a lot of extraneous stuff. Like Spridgets, they are designed down to the bare essentials. Even the luxo stuff like power windows and A/C is stripped down.
Alfa, being Italian, puts as much emphasis on the way a given part <span style="font-style: italic">looks </span>as how well it <span style="font-style: italic">works</span>, unlike the more prosiac English engineer's way.
Alfas are engineered better overall, because they didn't have to compromise by using a common MOWOG parts bin. They spent time on details like getting the top to work, for instance.
Unlike the bargain-basement Spridgets, Alfas are pricey. Not as pricey as the "other" Italians in its league, but definately a step up from MG money.
Both cars are easy to work on: all the mechanical bits are accessible and garage-friendly.
Both cars are dead-reliable <span style="font-style: italic">if </span>you look after them -- and both need looking after. Lucas and Marelli had their own way of doing things, and if you do things their way, you'll be fine. Even the oddball SPICA fuel injection works well if you keep up with it.
Both cars have their endearing quirks: you put oil in SUs, you scrub an Alfa's fuses with a toothbrush. You adjust a Spridget's valves with a screwdriver, an Alfa's with shims.
Both are a blast to drive in their own way. Spridgets are limited by gear ratios, not so the Alfas. Both are perfectly balanced and take the twisties well. Alfas work much better as long-distance cars and love the Interstate.
Alfas need to be driven often and hard. It's not a car you can coddle on the weekends.
Oh, and like Spridgets, Alfas have a very loyal and friendly user network.
Did I miss anything, Doc?
