It does look great I agree but I think you need to becareful of falling foul of link link farming which I believe will be clamped down on in future Google algorithms.
Bearing in mind linking to other sites can be an endless tasks as the more the better (generally this is true for related sites but a few high PR non related sites won't harm you) your page will in theory continue expanding forever. I would look forwrad and split that page down in to catagories. This is for a number of reasons...
1) Google has trouble spidering more than 100 links per page so could be loosing some valuable relavance if it doesn't spider all the outgoing links.
2) If this list continues to expand and google tightens down on link farms it could be seen as one and incur a penalty. All said and done I think this is remote as they are all related links.
3) More valuable anchor text. If you break the sections down and can use keywords in your anchor text then all the better for your site. Especially if for example you used the word 'Nissan modifications' which could be useful words for your site. Under that would links to Nissan Modifications so the page would be very very relavant to the link which is good. Obviously there is a line to how much effort you can put it in. the above example maybe going to the n'th degree and too difficult to manage.
4) You can have a general links page and get some high PR quality links in that arnt related to your site so won't dilute the relavance of the links in the more relevant areas e.g. shopping directories or partnerships you enter into (maybe with friends that have helped you with your advice etc

)
5) In the future if you do come to a point where you need to split your not going get a whole host of people complaining their link has disappeared cause you moved them all.
I would put 5 or 6 catagories, not more as it still could look like a farm, put the links in their and save the actual page you have existing for extra special link exchanges as it is a high PR. Some sites will only link to one click from home page or PR4 minimum etc so using that page could be good sales for special arrangements.
Does all that make sense?
If your not aware, using underhand techiques to further your SEO is can be termed Black hat SEO techniques and include hiding link pages with Robots.txt or javascript so it looks like everyone is linking to you and your so good you don't need to link back and so on. Thing is it's a dog eat dog world out there so it depends on how far you would go with your morals. For me I don't mind getting very general links to unrelated sites that have at least a PR of 1 or 2 and then kind of, erm, how should I say, editing the general page so there is more room for some more after a few months. The big link farms won't monitor and you get a free link when google spots it's dropped off your page and so on. A lot of these pages have a massive number of links so not that useful anyway but still better than a kick in the teeth. It's the only way you can get 1000's of links without having a massive link farm so many others must do the the same. Not the nicest thing to do but be assured people will do it to you!!
All IMHO so comments always welcome.
