You need to bear in mind that a pizza delivery job will absolutely thrash the car. Either buy cheap and scrap it when you wreck the suspension, or buy cheap and learn how to maintain it, because you will be doing suspension and brake work on it. The front suspension on my '97 Golf estate with 140k is absolutely shagged, mainly from doing pizza delivery, but also because I'm pretty sure it's factory and it's fairly tired at 140k. I'm waiting till I quit in a couple of months to totally rebuild the front suspension. My previous car, a 52 plate Renault Scenic with only 80k on the clock, simply couldn't keep up with pizza work and just broke. Both rear shocks snapped at the heads (common problem with those though), and I broke two engine mounts, a gearbox seal, the gear shifter linkages, and a driveshaft, all in less than three months. I decided after that mess that I was going back to VW. Sort yourself out with a 90's Polo/Lupo/Ibiza/Arosa and it should look after you fairly well.
