The price has increased but Martin Foster's dream of creating a New Zealand sportscar remains in production.
Foster had originally hoped the hand-built Zetini Haast Barchetta would be finished about Christmas this year at cost of $165,000 (excluding GST).
He revealed this week that necessary changes had pushed that finish date out to "more likely late January". The cost had increased to about $214,500.
Among the changes is the switch from a Tremec gearbox to a Getrag unit.
"Not only does it [the gearbox change] free up a significant amount of space in the cockpit, it has allowed me to design the gearbox ratios exactly for the car," Foster told Stuff.co.nz.
"Also, if anyone wants one for a specific use, ie track, I can tailor the ratios accordingly. The gearbox has the options of adding sequential gear change."
Foster said a downside of the changes were that they were now on to the third chassis as the rear suspension has been completely re-engineered.
Another change is that carbon fibre is now a body option, along with aluminium.
"The carbon option has come up due to the time it takes to make one aluminium body. It is not a replacement but an option.
"Carbon is lighter than aluminium, with the added bonus of carbon being stronger."
The first car, which is being built at a secret location in the Wellington district, will have a 6.2-litre engine, producing about 475bhp, and will have the option of a rear wing, which is another recent design change.
"I also have been asked about a left-hand drive version and the car is designed to be left or right-hand drive."
