Pioneer - Suppliers of excellent audiovisual components.  You really get value for money.  Have a look at their e-motion speakers.  Titanium cones provide excellent sound definition.  How do I know?  I have e-motion speakers in the front and rear of my BMW and they provide crystal clear sound whether on the motorway or travelling through slow moving traffic.

Alpine - If you after some heavy hitting components then you could do far worse than investing in some Alpine goodies.  I originally bought a head unit from them and was so impressed I decided that I had to invest in an amp and sub from them.  It has really completed my install and you can see photos of some of the bits and pieces on my Car page.

Mobile Car Stereo - I bought most of my equipment from here as it was extremely competitively priced.  If you are looking to start or upgrade your ice install I would recommend MCS.

Speeding - Have yet to use this company as they only deal with accessories but believe that their service is exceptional and with free delivery on most components it is well worth giving them a try!

Euro Car Parts - This is ideal for all BMW drivers as they produce catalogues tailored to individual marques.  They also do catalogues for Mercedes, Saab, Volvo, VW, Audi, Citroen, Peugeot and Renault.  Pop over to the site and order your catalogue today.

POTN - Provider of anything you could need.  Recently purchased some 10k boost from them and was impressed with the service I received.  Delivery costs are low compared to some of the larger companies.  Only paid £3.45 when ordering my 10k boost!  Very reasonable compared to the £10 most companies charge.

Max Power - The ultimate modifying magazine.  Tends to cater for newer cars such as the Saxo, Corsa and Clio but is worth checking out for ideas and tips.
