I always liked the 6000 awd. The Benz goes without saying. I really wish the awd system from the 6000 could have translated into the new for '94 Bonneville. I bought mine used in 1998, with 86xxx miles. It had the most basic mouse fur split bench, shift on the column spec, and was lacking the Pontiac Plastic cladding, but had foglamps and the indestructible 3.8 V6. It was painted in a colour that I can only describe as "cardboard beige metallic"- I could make the Bonny look just washed by cleaning the glass. In Grand Forks, ND, without a block heater and always parked outdoors, the Bonny could sit 3 days in well below zero temps and fire instantly. The colour and brand made me invisible on the highway, ran 90+mph often (old man car), never got tagged, much less ticketed. When I traded Bonny for a 3.8 Monte Carlo Z34, it had 382xxx miles with no issues and only normal wear items replaced. Rust finally ate the floors. I wanted to weep. As a front wheel drive car, it was brilliant. As an awd, I'd have put new floors in and kept the faith.
