A car is a machine that demands regular maintenance to stay reliable. When your suspension starts clunking, it eats into your tires and ruins the ride quality. Prices for these parts usually stay steady, but you can sometimes get a better deal if you bundle the repair with an alignment check in the spring when shops are less slammed.
You should aim to pay for the job in full, but if you need to keep your cash on hand, you can spread the cost out over time. Getting the work done now prevents more expensive damage to your steering rack or frame later on.
The 0% intro APR is a deadline, not a gift. If you still have a balance after 15 months, the bank will start charging interest on whatever is left, which will quickly make your repair more expensive.
