Hello, I am driving a new BMW Z4 and looking into 2008 Signature 100 as a weekend/collection car (maybe 30 miles each week). This particular car mileage is about 12k, fully loaded and excellent condition. It is selling for 65k. Is it reasonable? It says comes with high power 220v charging system. My garage only has 110V outlet. Will it work for me? It seems like 100 signature is cheaper than 2.0 and 2.5. Do you think 1.5 is more difficult to maintain in the long run? This will be my first E car.
