My hubby has a 2001 pontiac aztec with about 80,000 miles on it. It has been nothing but trouble. The air conditioner doesn't work and it will be about $800.0 to fix it. The transmission cost us 2500.00 to fix and now its overheating and he suspects it the head gasket. Help. We don't have a lot of money to buy another car but is it better to keep this one running or try to buy a "beater car". (We just drive his car to work etc never out of town)
