I think there a couple of issues here.
1) Discounts on new machines. Reiten cannot match the discounts offered by other dealers - and they are 100% open about it. They were/are "happy"

for you to buy elsewhere and bring the servicing to them. The only way they could price-match would be if the husband and wife owners stopped paying themselves salaries or stopped investing in the business so that it could grow.
BTW for similar reasons there are no winter servicing discounts such as NOG or Sycamore sometimes offer.
2) BMW were very good about allowing the fledgling dealership not to go "all corporate" with the extremely expensive black flooring and interior decor - including the workshop area. They probably would have gone bust on day one otherwise.
If BMW have called time on that generous arrangement (possible lobbying from their competitors??), then I can understand the reluctance to invest in the current showroom if they really want to expand to somewhere else. After all, they are getting more servicing work after the closure of Lind, Norwich.
I shall continue to support Reiten in any way that I reasonably can.
Update: The "corporate refit" was going to cost around £250,000. The profit margin on new machines combined with hit to cash flow on taking in customer's trade-ins (it may be months after you have paid the trade-in value before the traded bike is sold) made it not financially viable.
Reiten were the first to get hit with the demand.
Inhabitants of the Norwich area wanting shaft-drive tourers are flocking to Lings Triumph - or having to treck down to Sycamore, Witham.
Does anyone understand why BMW UK does not want to sell into East Anglia?
