Looking to buy a 94 civic DX 1.5 SOHC w/ 149K miles for $1500. Car is clean, drives strong. Has A/C, but guy says there's a leak and needs to be recharged ever 3-4 weeks. Any idea on if this sounds like a costly repair? If the compressor or condenser need to be replaced, is this difficult? I've replaced hoses, belts, an alternator, and helped with a head gasket replacement. But I've never worked on a Honda.

Thanks for your time. If buy the car I can see myself here often!
