I have a 1994 GMC Suburban that I bought new 220,000 miles ago. I replaced the transmission at 200k, but the engine is still doing good. No oil added between changes. I want to refurbish it and start over but everybody tells me that's a dumb idea. Does anyone know of a place I could send it and have all new "stuff" put in it? If I could paint it and replace the carpet and upholstery, new engine, transmission, etc., I would be happy to keep it another quartter million miles.
