At the recent 25th anniversary of Skoda’s merger with the Volkswagen Group, the Czechs decided to roll out three decades of Skoda vehicles for journalists to try. It was arguably a brave move, as the older models were clearly everyday working vehicles, with high mileages.

Skoda Favorit

Most popular among the assembled hacks were the three examples of the 1987 Favorit. I managed to get hold of the keys for the Favorit estate, more correctly known as the Forman.

Development of the Favorit was, in theory, overseen by the Czech communist government, so it must have been something of bitter pill for state-owned Skoda to have to go to Western engineering consultants for help.

Italian style house Bertone was heavily involved in the design, though Skoda developed its own modern monocoque body assembly. However, there was almost no effort put in on modern safety standards - as the car’s sub-900kg weight reveals.

Many years ago I ran into the VW engineer responsible for updating the Favorit. I asked him what he had done to the ‘platform’. He laughed out loud: "There was no platform. Just a structure".

Even so, this is remarkable well-packaged car. It’s wide inside and the room in the rear is very impressive. I wish I could say more about the space under the hatch, but the boot lock was missing. Slamming the doors - which are so light they seem ready to bounce off the lock striker plate - demonstrates the Favorit’s featherweight construction.

The 58bhp, 1.3-litre Skoda-developed engine is tappety but reasonably willing. The long gear lever has an ever longer throw, but once the car is rolling along the bare 68lb ft of torque is not an issue. Rather like an old Renault 4, the Favorit has a very comfortable gait and is - perhaps not surprisingly - very happy on the roads on which it was born.

The interior plastics might be a disaster, and the switchgear feels very cheap and crude, but you can absolutely see why this car was so popular across central and Eastern Europe.

Skoda Felicia

Driving the Felicia immediately afterwards - the VW-overseen model based on the Favorit - is a shock. Although this was a year 2000 model and had just 35,000 miles or so on the clock, it was a world away from the Favorit.

Introduced in 1994, just three years after VW bought into Skoda, the Felicia feels like a thoroughly modern supermini. Indeed, the example I drove felt very contemporary indeed. Although a bare 100kgs heavier in the lightest versions, the Felicia felt as solid and well-screwed together as the Favorit felt loose and floppy.

The fuel-injected engine was quiet, smooth and pulled impressively. The shift action was also unexpectedly meaty and precise. You might imagine it to be an entirely new car, but the Favorit is clearly still buried in here.

The short dash top and control locations give it away, and the key slot is still buried in the face of the dash to the left of the steering column. VW might want to run a rule over this Felicia because the interior space and luggage capacity remain impressive over such a compact footprint.

Skoda Octavia Mk1

The first-generation Octavia was unveiled five years after VW bought into Skoda and was the first model based on the then-new PQ34/Golf 4 family platform. The format of original Octavia showed how Skoda was allowed to be different.

A huge rear overhang might not have been elegant, but it meant that the hatchback and estate had the kind of super-practicality that rival Golf-class models couldn’t get near.

This 155,000 mile Octavia estate was the top of the tree in its day, with all-wheel drive and a six-speed manual 'box. From nowhere, Skoda was building the kind of practical, rugged, bit modern estate that was getting lost in the first stirrings of the auto industry’s premium boom.

The car I drove was well-used but clearly well-maintained. I spotted new seat belts and was impressed by the smoothness and refinement of the ride, which pointed to plenty of fresh suspension components.

Even so, this old machine had more than adequate legs for rapid motorway travel, an impressive long moon-shoot sixth ratio and unexpected refinement. Clearly, it was the sheer practicality of the first-generation Octavia that helped it gain traction in a market that then would have still associated Skoda with ancient east European products.

Last year Skoda sold 432,000 Octavias globally. In Europe, Skoda sold 216,00 Octavias. Compare that to Ford’s 232,000 European sales of the Focus.

Driving one of the original models, it’s clear to see that the Octavia gained market traction because this car had a very clear idea of what it was about, something it retains 20 years on and why it remains by far the best-selling Skoda.
