I've long had a love for British sports cars, and am actually coming perilously close to buying an MGB(meaning I'm zeroed in on a likely candidate).
After a lot of thinking, pondering, and looking, I've come to the conclusion that the "B"-or at least a pre-rubber bumper model-is sort of an ideal choice
1. It has the look, feel, handling, and quirks that are associated with this general class of car
2. They made a ton of them, which makes the cars easy to find and also relatively affordable.
3. Values are low enough that folks who own them tend to drive them regularly, meaning that there's a big community of folks with practical knowledge about keeping them on the road and all the issues that come with that.
4. Along the same lines as #3, quite literally virtually every part is available. Once could almost order a complete car from British specialists like Moss Motors. Most parts are relatively affordable, too.
So, at least to get my foot in the door of vintage British car ownership, the "B" seems like a good first step. I can then move on to a Healey, Triumph, or even(pipe dream) an XKE at some later date should I feel so inclined.
BTW, on the subject of Jaguars I had a really great test drive about a month back in an '01 XK8. The XK8 is technically classed as a GT and not a true sports car, but I can't say enough good things about it. The whole thing had a great, solid feel about it and superb ride quality(in line with being a GT) but still handled incredibly well-especially for a car over 2 tons. The book says that these should be around $7K, and if the seller had been anywhere close to that I'd probably own the car now. Unfortunately, he and I were WAY too far apart to come to a deal.
I've been very tempted by the prices on the '70s and '80s RRs I've seen(which I've looked at and admired pretty extensively), although realistically I've moved away from them just because that's not the sort of car that really interests me at this point in my life. In all honesty, I'm not crazy about the looks of the current(post BMW) Phantom. The "classic" Silver series models-in particularly the more recent and relatively affordable(now) Silver Shadow, Silver Spirit, and Silver Seraph have the unmistakable RR look and have class written all over them.
