Kinsey and his team have done this for a quarter of a century, and while it's impossible to quantify the money they've saved motorists and fleet owners by providing accurate figures for the most popular cars and their rivals each year, it must by now extend into many millions of rands.
Manufacturers and importers are very careful when pricing their spares because they know that if they're out of line with industry norms, it will affect their sales volumes and fear of repercussions in the marketplace frequently lead to significant reductions in prices.
They also frequently forward the reports to their parent companies overseas to illustrate that their parts prices are out of line with those of their competitors in this country. Kinsey compiles his report by anonymously querying the recommended retail prices of spares for the selected vehicles from authorised dealers, all in the same month.
The parts are grouped in three categories - service items, repair parts and crash parts - for each vehicle and prices are then compared with their peers, covering different market segments.
When parts physically differ enough to confuse the issue - complicated electric side mirrors versus simple manually adjusted ones, for instance - this is clearly explained, and where a manufacturer offers only an entire expensive component where its rivals offer simple replacement parts for repair Kinsey will highlight that.
The totals of each parts "basket" and the overall costs per vehicle are then shown as a total and as a percentage of the vehicle's purchase price. A clear winner would be a vehicle with a low price and a parts basket that costs a small percentage of that low price.
Kinsey says that some of the price increases since last year are astounding.
"Wheel rims in some cases are over R20 000 each, doors in excess of R15 000 and if your car is fitted with "intelligent lights" a replacement may be in the R30 000 to R45 000 bracket," he said.
Many manufacturers offer these in place of the relatively affordable halogen for their upmarket vehicles. These components are in the crash parts category and in general this is the area where there has been the steepest price increase."
Service and repair parts have not been as badly affected, probably because the manufacturer pays for these under a service or maintenance plan for a few years.
Here are the top three contenders in each of the nine categories with the total cost of all 34 parts for each car. It's interesting to note how much the French manufacturers have improved.
