Would this kind of car be a lot more expensive to run, than, say, a honda or a toyota of the same age?
so far ive found the price of parts very reasonable,,euro parts seem to run cheaper then say japan imports
1)the price of spare parts, regular wear stuff like timing belts, hoses, CV boots, alternators, ignitions, water pumps, etc.
timing belt is like 14$,cv boots in the 20$ range (i think) water pump is 40$,,,all in all not to pricey
2)Are automatic transmissions on these cars generally decent and reliable
yes,,tho some seem to slip/ or hard shift (not shifting at right rpm) if theve sat for awhile,,,also it depends on how much the car was abused
3)Do these cars come with timing chains or timing belts (is the engine an interference engine
YES they are interference engines with timing belts,,,,i suggest that no matter when the last owner says it was changed to change it anyway,,they are sohc(single overhead cam) engines so the timing belt isnt to hard to change,,make sure you/your mechanic does the tensioner and water pump while there at it.
