Re: Leather interior
By trade I'm a trim developer. I develop interior seating for the likes of Ford, Jaguar etc. etc. I'd be surprised if the £450 would include full leather seats as if they use the correct automotive grade of leather this would cost anywhere between £300-£500 + VAT(this cost is purely for the leather and is on the lower end of the leather quality scale). The cheaper option for them would be to use upholstery leather but unfortunately the wear characteristics of this leather are not very good and within a few months you will start noticing unacceptable wear to the bolsters on the drivers seat in particular. Upholstery leather also gives off amines. This chemical will through time start to stain any lighter fabrics that are in your car(possibly parcel shelves for example). These chemicals have been known to turn ivory nylon on roof linings yellow within a few months. On top of the cost of the leather they still have to cut, sew and assemble the seats. This from experience takes hours of skill if it is to be done correctly. If you require new covers for your vehicle(including doorboards/armrest/headrests) you are looking at a minimum of £1000 - £1400 to get it done properly. Some place will charge anything upto £3000.
Trust me, you are better paying out good money for a personalized set of covers or buying a second-hand set of seats and living with the slight wear that they come with.
Go onto ebay and look up item number 130225740757. If you're not careful you could end up with covers that look as bad as these. I'm currently developing new leather covers for the same car that this ebay link will send you to(Mitsubishi FTO). When they are finished they will look better than anything Mitsubishi has ever produced.
I'm not suggesting that the stated Alfa Specialist will supply you rubbish but what I am saying is that for under £500 they will not be of the same standard as an original set of Alfa seats.
