Bumper to Bumper Radio, the car guys on KTAR, 92.3 FM in Phoenix, AZ, broadcast every Saturday from 11:00 am to noon. On this show, Dave Riccio of Tri-City Transmission in Tempe, AZ provides tips for buying or selling your used vehicle. Also on this show:

• The cost of the repairs that I need seems to outweigh the value of my car.
• 2000 Nissan Xtera: My air conditioning went out on my car and due to the high and low pressure hoses that are leaking. Should I get hoses that are rebuilt or buy new?
• 1997 Ford Escort 114,000 miles: The a/c seems to have problems but I'm still interested in buying it and have it repaired. Is this a good idea?
• Always have someone you trust thoroughly inspect the car you're interested in buying.
• If buying a used car, ask for a pre-purchase inspection on the vehicle.
• 2000 S10 Blazer 180,000 miles: Sometimes the car idles so low that it will just die when I come to a stop.
• 2000 Chevrolet Silverado: The leather on the drivers seat is torn. Do you recommend someone who can help me fix the interior?
• 2006 Nissan Armada: Everyone once in a while I'm losing break pressure and the light goes on. There doesn't seem to be anything that will fix this.
• 1995 Geo Prism 187,000 miles: The list of problems with this car seems to go on forever and I'm not sure if I should hang on to it.
• What is the Repair/Replace Calculator?
• 2003 G35 Coupe: There's a squeaking noise coming from the dashboard. What is that?
