it’s just one long sentence. Is it yours? In my experience I would start an ad with with an open paragraph listing reason for sale, ownership details etc. Then I would list via bullet points the options and upgrades, then detail the service history bullet pointing each service, with mileage, date and who did it. Then finalise and close with a statement around the quality and condition of the vehicle “sell the sizzle not the sossig”
Apologies if it is your ad and you don’t like my criticism. Just personally I’d skip by that car if I was looking for an R35. First thing I read was this chap is servicing this car himself, it’s modified and my head hurts as that’s the longest sentence anyone ever wrote.
