Arnaud,
Hmmmm...check the 3
Arnaud,
Hmmmm...check the 30K reciepts to see if they replaced "ALL" the seals, fuel filter, tensioner bearings. A 30K that truly addressed hidden issues should have cost around $5K. Check to see if wipers work, AC, Radiator Fans.
I have a 2 owner 77 that I serviced for 15 yrs with only 10K miles that went into frequent service last Jan. when the 2nd owner bought it. I've had a long string of nagging problems pop up routinely from this new frequent use. Such as Rad Fan Bearings siezing from dried out lube, Wipers so slow they were useless, AC expansion Valve sticking closed requireing replacement (and Dryer) fuel hoses cracking from inside out, heater valves plugged from the inside, etc.
Putting this garage queen back into daily service has been far from trouble free or cheap. So a heads up is probably in order here. Many of the problems I never anticipated becase the car "looked" brand new from the outside, but was suffering from lack of use on the inside.
