There is a blue 130 hatch on the bay at the moment for just under 8 grand don,t know if that,s about right for a good one. As chris m says they are hard to find now, don,t know how many genuine 130,s are left now may be few hundred or so saloons and hatches. If you find one make sure it is a genuine 130 they are easy to fake and i have yet to see a log book for a 130 where it says SRI 130. Good luck in your quest.
I would love to find another sri 130 saloon but the 1 I had was like a dark red colour I can not find any pictures of 1 in that colour anywhere so must of been an unpopular colour back in the day.
The cdi is a great car esp having ps, central locking, electric Windows& mirrors. I have 2 and one in the same colour as yours which needs a bit of work.
