You can't be serious! A brand new hundred thousand dollar Mercedes will get a flat tyre if you drive over something sharp enough! Regarding the other problems you describe, what do you expect for a car that has covered 190,000 kms? It is normal for any older, high mileage car to need attention to brake pipes and the exhaust; the salt used in the winter in northern countries will slowly eat away any non-rustproofed metal on the underside of the car. So the only real problem you had is the ignition module. One problem isn't bad for a well used car.
