I am going to get an Audi A8 4.2L D3 from 2003 which my dad already owns. I know that it is quite old and will need some maintenance, he have fixed a few parts but I was just wondering if anyone knows what needs to be changed on this car even if the part has not broke yet? I would also like to do some aftermarket mods such as bodykit, bluetooth mod etc. does anyone know a good site for this and what parts to buy? Apart from that, is there any engine mods can is possible on this kind of engine? I would like to know as much as possible about this car. Is there possibly any mods to make the handling and things like that better? It has 23.000 miles on it

Wheel spacers and maybe a trunk lip spoiler. Check brakes for corrosion. Check battery replacement date.
For the rest -- save pennies for maintenance. Use good tires.
