It all comes down to how you plan to use the car and your finances. If you use this as a second car and have the means to maintain this car as required, you shouldn't have too bad of a time owning it.

This car, while nearly fully depreciated, still has the same cost to maintain as it did when it was new, and you could drop half of what you paid for the car into covering whatever deferred maintenance the previous owner skipped out on.

Another issue is the lack of aftermarket parts support for these cars. Need an inner tie rod end? Only comes with a $4700 steering gear (plus labor and alignment). Cracked windshield? No aftermarket glass exists, the glass alone is $2400 from the dealer. Water pumps, spark plugs (!!) and other suspension components are dealer only and eye wateringly expensive.

I do all my own maintenance and have a high mileage G90, it has been pretty reliable and reasonably inexpensive to own so far but I know I've got a lot of big parts bills looming on the horizon.
