Its probably best for anybody who may be interested to come and have a peek, ive only had the 90 since sept 07 for use on a few camping trips and couple of green lane runs, majority of the upgrade work was done with the previous owners and any repairs ive had carried out by a landrover specialist garage due to myself not being to mechanically minded. Advice on the air filter was by another garage I use occasionally. But back to the topic if anybody could throw a few guestimates about then ill know what to expect or ask for.
