Matt,
The XK150 FHC is a wonderful car. Practical, sporty, fun to drive, powerful, and posses many mechanical and comfort features not found in the earlier XK models. If you can mange a Model T, you'll get use to the Moss box. I've owned a fair number of different British cars, and currently own 3 Jaguars (E type V12 OTS, and 2 XK150 OTS). And, until recently I owned a XK150 FHC 3.8L two carb O/D car. I'm of the opinion if you own only one Jaguar, the best is the 3.8L XK150 FHC. The 3.8L two carb is nearly as powerful as the 3.4 S model, and with over drive the car sits down at about 90 and cruises along. Yes, the steering is heavy, but only at lower speeds, Just drive fast everywhere. Now, the car in question looks nice, but as in all British cars, the devil is in the details. Rust, the great enemy, can be big dollars in any Jaguar. Also, matching numbers is a big deal in Jaguars as it comes to price. Driving the car, it means nothing. So, if you can find one that is a good car that isn't matching, the price should be about 20% less than one that is matching. I do think the car is about 10-15 grand over priced. I sold my very nice 150 FHC last summer for 40. Keep looking, as its always best to buy from a fellow enthusiasts rather than a dealer.
