If i was to add another vehicle specially if you are looking for safety,I would go with an SAV e53..the fact that is safer and reliable to put on stuffs shopping,foods,goodies than an e46 on trunk space wise....as far as gas..i would go with 3.0i rather than 4.4i or 4.8is...your looking for safety as not for power...
