It's a great engine! You won't have any issues keeping up with traffic.
As with all Landies... If it's properly looked after; it'll treat you well for many miles. If you get one, get yourself a nanocom (or a friend with one). Consider it another tool in the box to help fix things. Don't let the sensors/electronics scare ya. It's not that bad at all... I've had one for the last few years; and it's been fantastic.
