nice....

i didn't test drive my 12 50i either but i did have an 08 X5 3.0.. the ride was great but lacked real power... i just knew the 4.4 would make a huge difference... and it did... had concerns about going to an 8 thinking i was going to have to refill every other mile... not really a concern anymore..

it gets thirsty but not as bad as i expected... and the extra hp is well worth it...
