Hi I’m new to this forum, but had some questions that I’ve been trying to research and I feel like I might as well ask on here. So I am looking to buy a 2010 Mazda 3 2.0 5 speed manual with 104,000 miles for school travel. So first off the over all appearance is decent.The paint on the roof and hood is a faded and oxidized but I feel like I can make it look a lot better with a good buff and polish so not too terribly concerned, the interior is okay. General bit of wear and tear although it is an 11 year old car. Under the hood is a little dusty and dirty. The car drives very well and doesn’t sound off in any way. But the check engine light is on for an O2 sensor as well as ABS and traction control warning light. Are the warning lights for ABS and Traction control of any concern? Or are these just stemming from an ABS sensor gone bad? Over all he is asking 3500 for the car. Is this a pretty good over all price for the car? Thanks in advance.
