Should I buy a car on credit right now - is it worth it?

Don't take out a loan just "because the finance person said so" - figure out your financial situation yourself. Car loan rates are pretty high right now, so it's worth comparing: maybe you could save up part of the money or buy a cheaper car instead of paying extra in interest. The main thing is to calculate whether you can handle the monthly payments without stress, keeping in mind that besides the loan there's insurance, gas, and maintenance. And definitely read through the contract terms yourself - don't rely on the seller or the credit specialist.
