My car history is pretty boring:
1) Vauxhall Nova 1.2L. Only issues were having to have a new head gasket and a new battery. I had to call the AA out once as I ran the petrol down to the last sip and got a carb full of gunk. Ran it for 5 years.
2) Rover 623SLi - no faults at all in 2 years of ownership
3) IS200 Sport #1 - no faults at all in 3 years of ownership
4) IS200 Sport #2 - timing belt and water pump changed at the normal interval, other than that, nothing (6 years ownership)
5) IS250 SEL - battery replaced after 10 years, aircon compressor replaced, exhaust back boxes replaced, water pump replaced (12 years ownership)
So only the Nova let me down, and that was self inflicted.
