Hello again, the car has been on a couple of outings to sort out a few things. One of the most annoying is a vibrating rattle in the gear shift lever when in Drive, move it into 4 and the rattle disappears. I cannot drive around in 4 all the time so I will have to fix it. Any help will be welcome , also how do you adjust the height on the seats? I notice there is a strut of some sort under the seat but I cannot find a lever to operate it.
