Update:
Just changed the oil for the first time. The Chevy dealer quoted $69 for an oil change! I got it done at Jiffy Lube for $32! That engine appears to use a quart every 2,000 miles, which is comparable to the 454 chevy in my last motorhome. I can tell that I am a little more tired after driving it in traffic, but the difference between the B+ and a regular commute vehicle is really minimal. One difference I seem to notice is that other traffic assumes I cannot accelerate as well as other cars, and pull in front quite a bit. Parking is pretty easy also. Last week I parked in a parallel spot, and cars parked on either side of me with only about a foot of clearance on each end. Though it took several "back and forth" movements I suprised myself how easy it was to get away. The back steps protrude a few inches, which gives some additional movement when turning sharply in both directions. Also the overhang swings the rear more.
I am looking at replacing the rims and hubcaps with aftermarket wheels (aluminum or stainless). I would get the stainless liners, but am concerned about wheel balance with those - especially the rear wheels. Any ideas on replacement wheels for $5-700?
