Faults:

Replaced front exhaust down pipe.

Installed rebuilt CV axles (maintenance).

Replaced left & right front ball joints (kinda loose).

Replaced leaking rear shocks with struts off a Jetta.

Odometer has stopped working (so exact mileage unknown), & sometimes the speedometer lighting goes out.

Replaced clutch after throwout bearing got stuck.

Replaced front & rear brakes & wheel cylinder (maintenance).

Replaced broken emergency brake cable.

A/C compressor failed; replaced with a used unit.

Leaking A/C hose and pressure sensor replaced.

Noisy left-front wheel bearing replaced.

Battery replaced (it was way old).

Installed a fuel filter pre-heater (driving in about -8 deg F weather one time, the fuel filter nearly waxed up on me, this is cheap insurance).

Replaced heater core that "smelled bad" (still not sure it was the core or the hose connections that were leaking).

Replaced belts, timing belt & bearing (maintenance).

General Comments:

After driving a diesel Rabbit for a number of years, this Quantum seems about twice the car the Rabbit was (has A/C, power steering, turbo boost, power windows, all the things the Rabbit lacked), but still gets 41-42 MPG+ on my daily commute.

Looking at the list of repairs, it's been somewhat on the unreliable side -- but considering it's a 31-year-old car with an unknown past history...

Has never failed to start, but I do plug in the block heater when it drops below 15-20 deg F; (no use adding unnecessary wear & stress to the motor/electricals).

A bit labored accelerating from a standstill; but once out on the highway it's like the Starship Enterprise ("warp 6, Mr. Sulu") -- and easily climbs Colo. mountain passes.

Faults:

Very little, actually. Most of my trips to the garage were for preventive maintenance.

The A/C compressor died around 140,000 miles.

The air intake had to be replaced.

The fuel pump relay died around 165,000 miles.

Most of the parts I replaced were hoses, belts, tyres; things that are subject to normal wear and tear.

General Comments:

Great car. Very reliable. I owned it for 11 years.

Very comfortable to drive. I owned 3 VW Dashers prior to this car. Good cars, Dashers, but this one beats them.

It is a bit more expensive to repair, though. Probably the best, most dependable car I've ever owned.

Faults:

The normal part replacement's of a car this old.

It needs a new paint job.

I did have to replace the heater core last year.

General Comments:

My point is my car is 20 years old.

It is cheap on gas.

I enjoy driving in it and riding in it.

It hasn't really left me sitting yet.

I am going to paint it and drive it for another twenty years.

Faults:

I thought when I purchased this car that I was getting a quality vehicle. It was until about two years later when it started to nickle and dime me to death. The heater core went out at around 70,000 miles. The cv boots were replaced three times. The drivers side wind shield wiper broke at 40,000 miles. The antenna broke at 80,000 miles. The tape player broke at 50,000 miles. The gas mileage was good, and the engine was tight. Other than that, it wasn't a good car. No more Volkswagons for me.
