ML320CDI Airmatic

Hi. My first post is a bit niche.
I am looking at a ML with off-road pro pack. I have had a test and it seems to take about 2 minutes to go from low to extra high.
Maybe it hadn’t been used in a while but the dealer says they replaced the compressor. Is it possible it’s not powerful enough?
Anyone know how quick it should be?

I have a 2011 GL and it does take a while. Haven't timed it but 2 minutes wouldn't surprise me. Mine wouldn't get to the top originally so I had the compressor replaced. It's still not fast but as long as it passes each stage with reasonably equal timings, it's probably working as it should.

Thanks for the info. As it happens, the car was a slight letdown in other areas anyway so have passed on it.
Saw a cheapish GL on AT. Tempted but they are a big old lump and the wife got intimidated by its sheer size.
