I purchased a 2000 ls400 with 113,000 miles. It needs a rear subframe, radiator, maybe new shocks as the new shocks on the car now ride hard and the brakes are spongy. I paid $5,000 for it but am having second thoughts about whether I should keep it. Two mechanics said the car is in great shape but at the end of all the things I need to do to it I’ll own it for $7,000.00. Thoughts please?
