Is Porsche a good quality automobile?

Hell yeah! It is European made.

Of course it is. it is a European car

Absolutely. As with most cars, if it has not been abused. Many people collect them. Depending on your age, better check costs for insurance.

It most certainly is. Porsche is are German cars, and l have found that every German car I've been in is really reliable. Of course, it is not necessarily about how the car is made in some factors. If you abuse the car, or do not take care of it, then it will lose it is quality, and become unreliable.

probably why they cost $100000000000000000000000000 dollars

l think they are,,,,,i have one Cayman S,,,its doesnt cost $100000..the service and spare parts are truly expensive

Depends on the model & age & any previous owner, my 911 is awesome, quick & reasonable on fuel but had a few problems. My last service cost £2000 on a 4yr old car which included new rear discs, etc. Older 3.4 engined 911 is have problems with the Rear main Seal (RMS) which can cost u big money if it goes pop, tyres for these cars r expensive too.
Someone in the trade told me Boxters have had all sorts of problems so depends on the model.
Porsche is making a huge profit at the moment from a loss not so long ago, some of this is due to them churning cars out like the Japanese so the build quality on some models has suffered.
However, saying all that, they r cracking cars & yes, u should buy one.
