I am based in the Sevenoaks area in Kent, we are about 10 minutes from junction 5 off the M25, 15 minutes from junction 4 on the M20. Easy to find and easy to get too.
For those of you that are a long way away, then Gatwick is 40 minutes away and I will pick you up for the airport, normally in the car that you are buying so you can do a really decent test drive.
Sevenoaks train station is only 7 minutes away and I am happy to pick you up from there as well. Sevenoaks Train station is 30 minutes to Charing Cross. Otford train station (10 minutes away) is 35 minutes to Victoria.
