335i/d ain't a weekend car in my opinion, it's an everyday car.
If I were buying a car to drive low miles I would be much more concerned with depreciation than fuel economy.
M3/5/6 would be a better long term investment. Naturally aspriated V8 or v10 would liven up a weekend for me..
Car: 2010 Jaguar XFR (Stock - For now)
Gone but not forgotten: Highly Modified E90 335i LCI M Sport Manual (circa 480BHP/500lb ft)
