Cheap rental cars can be found easily if you don't mind having a big car and a new one. Discount car hire are possible most of the time with smaller vehicles and even with used cars. But for car rental discounts, check with the compaby directly, as prices might be cheaper on weekends or maybe for long period of times. A cheap car lease is therefore possible but you must shop around and see what are the best deals for you. The cheapest car rental dealers might not be everywhere like airports or train stations, but there are sure some in city centres of major cities. For cheap auto parts, there are some who deal only over the internet and you can even check on Ebay for that. Others will sell used parts, and if that's what you are looking for, you'll end up saving quite a bit. For a discount car audio, you can try your luck at car dumps since a wrecked car can still have great intact parts like radios.
