I ran my LSE as a daily driver doing about the same mileage and it was by some distance the best car I`ve ever had. If it is HPI clear, has a decent service history, reasonable mileage. and you can do basic maintenance yourself it could be a good buy.
I`d check the chassis , inner wings, rear arches (particularly the C pillar. rear arch join), the seat belt mountings and the floor very thoroughly for corrosion. Both tailgates as well - they all rust, its just how much and how fast.
Also all the electrics - don`t expect it all to work but so long as the non -working items don`t matter then it is a 20 year old car after all. If there is no advisory sheet with the MOT you should make sure there were actually no advisories - they are next year`s problem and at this price it doesn`t take much to make a repair uneconomic. Get some insurance quotes as well before you buy, its gone a bit stupid this year
If its your first RR - be prepared for an addiction, nothing else drives like one or feels like one
