www.synlube.com/  This oil was used in Space shuttle and Mars missions, 150K
drain interval, yes sounds a lie but it's true, filter needs to e  changes
every 50K miles though, and most important they recommend to use operating

www.wheelskin.com    Natural leather steeringwheel covers, paints, etc I
just had leather cover so I cant comment on anything else they sell.

As of myself, I want a new Ford hybrid, I am partial to both Ford being

Snetra after modification/reducing weight is a 40+mpg vehicle, cheaper than
mass transit!!)
