C70 Purchase advice

Dear community, I’m already here, but with my V70 XC I, which should not be the topic here. I ask you for your advice regarding a vehicle, which I would like to purchase additionally. It is a C70 with the following basic data: Coupe 2.3 liter / 176 KW (which engine code B… is this please ?) First registration : 05/2002 5-speed – Automatic ! (which transmission type ?) Sport suspension original, i.e. 15mm deep Triton 18″ with 235/40 R18 rear-view warning system – but now it comes, namely inside as good as naked… no SD no on-board computer ! no cruise control no DolbySuround or Navi no electric seat adjustment – but has leather sc-901 – has an e-prom performance increase lt. Messblatt 416nm / 278 hp …and last but not least 1 hand 60.000km ! 12x service…at Volvo, namely every year and looks really slick. ……we don’t want to talk about money, but what about the vehicle configuration and this performance increase to keep ? Thanks e times in advance for your comments. Greeting vauviernull (because it started here )
