ajgoodfellow, my advise to you is, find some cars mentioned here and test drive them. MG's, ST200's, and the rest, at the end of the day it is YOU who the car is for, nobody else, whichever you like is the one you should buy, yes they may have mechanical issues, or look like a dolly trolly but at the end of the day you have to buy it, run it, service it and keep it.
I was told about the K-Series headgasket problem before I bought my old 1.4SEi and sure enough it went, I had it reparied and then no more issues with the car at all, but at that time it was a car I really wanted, so I had it.
Bit older now so I have moved onto a more refined car, refined in build, performance, comfort just generally a step up from where I was at which it is all about, onto big and better things.
If you get an MG I'm sure you will be happy with it, same said for an ST200, end of the day its your choice mate, we can only "Try" to provide you with information about the said car and alternatives, rest is up to you.
