Hope your enjoying your new purchase ,
If your having the problem when cold to get 1st& Reverse a lot of cars do that you need to warm the car up a bid before driving.
If it’s all the time you can adjust fairly easily.
I have driven the car you bought my self and I must say I didn’t have any problem engaging gears , also your seat adjustment was working .
This particular car has been most of the time kept in storage by the previous owner , the car will definitely benefit of some more regular driving.
If you still have problems with the gears you can call in and I will get one of my technicians to adjust for you and the only othe think it can be there is a small bush on the Pedal of that has worn or collapsed can cause the problem your reporting.
