Yep, the 1098/1159/1256 engines had a habit of doing that - fuel line connection to carb over the exhaust... My HA Van set fire to itself in that way. I still maintain that the Chevette was crap though... even in it's day it was basic compared to the competion - no sensible engine upgrades, trendy rectangular lights that, er, didn't light, and no reclining seats.
Go on, get back in one for a daily commute and tell me it's good!!!
I have a personal opinion that car design hit an all-time high around the mid to late eighties - they seem to rust less than cars before or after, go on for two-three thousand miles easily, feel solid, well appointed without silly electronics (window switch not working? Sorry sir, that comes as a sealed unit as part of the door)...or maybe that is just the VAG group.
Back on topic... does it still apply that estates tend to be in a lower insurance group than saloons, or did Audi kill that with their (rather good) turbo quattro concoctions?
